The total surface area of the object shown in the diagram is 164 inches.
<h3>
What is the total surface area?</h3>
The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object. The object shown is the net of a cuboid.
Total surface area of a cuboid = 2 (lw + wh + lh)
where:
• l = length
• w = width
• h = height
2 { (10 x 3) + (10 x 4) + (4 x 3)}
2 (30 + 40 + 12)
2 x 82 = 164 inches

Answer:
The speed of balloon is 0.16 m/s.
Step-by-step explanation:
BC = 300 m
AD = x
AB = y
time, t = 3 min = 3 x 60 = 180 s
By the triangle, ADC,
![tan 15 = \frac{AD}{BC}\\\\0.27 \times 300 = x \\\\x = 80.4 m](https://tex.z-dn.net/?f=tan%2015%20%3D%20%5Cfrac%7BAD%7D%7BBC%7D%5C%5C%5C%5C0.27%20%5Ctimes%20300%20%3D%20x%20%5C%5C%5C%5Cx%20%3D%2080.4%20m)
By the triangle, BDC
![tan 20 = \frac{BD}{BC}\\\\0.36 \times 300 = x + y \\\\x + y = 109.2 m](https://tex.z-dn.net/?f=tan%2020%20%3D%20%5Cfrac%7BBD%7D%7BBC%7D%5C%5C%5C%5C0.36%20%5Ctimes%20300%20%3D%20x%20%2B%20y%20%5C%5C%5C%5Cx%20%2B%20y%20%3D%20109.2%20m)
So, y = 109.2 - 80.4 = 28.8 m
Speed of balloon = 28.8/180 = 0.16 m/s
To convert the 10 into 6ths, multiply 10 by the denominator of the fraction to give 60. Put this over the denominator to give 60/6. Then add the 1/6 to give a final answer of 61/6
